What are you talking about? They didn't train a model for this. That's why it's so impressive.

  Quoting from the paper, The only training required in our method is to con- struct linear models that map fMRI signals to each LDM component, and no training or fine-tuning of deep-learning models is needed. ... To construct models from fMRI to the components of LDM, we used L2-regularized linear regression, and all models were built on a per subject basis. Weights were estimated from training data, and regularization parame- ters were explored during the training using 5-fold cross- validation.

    Ah. This makes more sense. Thanks.
